This month is the "Drop Dead" point for AT&T's 3G cellular networks. There are numerous fear-based stories circulating, predicting the end of the world as we know it, loss of life, plagues of locusts, and halitosis for those whom aren't willing to spend the money needed to avoid the possibility of not being able to make the cellular industry a few extra billion.
Here's a statement from the FCC:+____________________________________________________________________+
If your mobile phone is more than a few years old, you may need to upgrade your device before your mobile provider shuts down its 3G network, to avoid losing service. For more information on your mobile providers' plans for 3G retirement and how you can prepare, contact your provider directly.
What is happening? Mobile carriers are shutting down their 3G networks, which rely on older technology, to make room for more advanced network services, including 5G. As a result, many older cell phones will be unable to make or receive calls and texts, including calls to 911, or use data services. This will affect 3G mobile phones and certain older 4G mobile phones that do not support Voice over LTE (VoLTE or HD Voice).
